'To all whom it may concern,- i

Be it know-n that I, BARTON H. JENKs, of Bridesbnrg, in the county of Philadelphia and Stat-e of Penns lvania have yinvented certain ning lvlachinery; and l dohereby declare that the followingis a full, clear, and exact descrip- -tlion thereof, reference being. had to thel ac- Figure 1, Plate l, is an elevation of one side ments applied to it, showing the spindles upon ing 1nechanism, in the vertical 'plane-indicated by red line .e .v in Fig. 1. Fig. 3, llate 2, is a depressing the spindle-carrying rails. Fig.-4, Plate 2, is an end view of the heart-cam, traveling tooth, vibrating toothcarrying arm, and devices for adjusting the tooth automatically sect-ion taken through Fig. l. in thevertical plane indicated by line z :f thereon, looking toward the mechanism for moving 'the spindlecarrying rails.

Similar let-ters of reference indicate corresponding parts in the. several vfigures.

The machine which I shall hereinafter-describe is adaptedrfor communicating a slow mot-ion to the drawing-rolls by the employment ofa worin-screw directly upon the shaft of the cylinder that drives the spindles, said worin-screw and its tangent-wheel, andthe bearing or step of the shaft of this wheel, bei'ng arranged to work in a bath of oil, which 'will prevent undue friction upon said parts. By thustaking a slow motion directly from the shaft of the main cylinder, complication of spari-wheels o? various sizes are obviated in obtaining the result stated.

The machine is also adapted for producing =cops, having their ends conical, with bindingthreads .constituting the layers in such conical ends; employing for this purpose a cam which is of a heart shape, and whose axis of motion is ohliquetoitshighest and lowest points or" throw, and using, in conjunction with -snch canna tooth lwhich traverses longitudinally upon the surface of the cam as the latter slowly rotates, and which is applied to a.vibrat ing arm that-actuantes.' the lifting-arms of the spindle-rails, as hereinafter explained.

In the machine which Ishall describe a uniform distance is maintained between the traveler-rings and drawing-rolls during the 'operations of spinning and winding, and `a given distance is maintained during said operations between the guide-wires and the rings -or travelers, and also between the drawingrolls' and said wires, as will-be hercinat r cxplained.

'ro @mn-,1e others skiued in the am@ under- 'stand my invention, I will describe its construction-and operation.

Intheccompanying drawings, Figs. l and 5, Afrepresents the freine-of the machine, which may be made for receiving spindles on both sides of it, and constructed in the usual wellknown manner of constructing frames for rin rspinning machinesf In the middle ofthe width -of this frame A, and supported at its extremities in suitable journal-boxes on the endsof this frame, is the mai-n shaft B, which is arranged in a horizontal lplane, andl provided--' bracket orau'xiliary frame, A', and upon this extension of the vshaft* Bare placed a Wormwheel, b, a driving'belt pulley, D,a'nd a loose pulley, D. The-worm-whecl or screw b engages with the teeth .of a tangenti-wheel, b',

which is keyed upona vertical shaft, E, and this worm-wheel, together with its' tangentwheelb and tlle'step-bearing of lthe shaft E, is-arranged within'an oil-box, E', as shown in' Fig. 2. This box-EV is supported in a suitable manner upon l'the frame A', and provided -with a closely-fitting cover that consists of two hinged sections, El, vby raising which access can 'be had to the interior of the box. This box E is designed for containing oil, so that the wheels b b' and the step of said vertical v shaft will be well lubricated. The upper part of the shaft E is sustained byabracket secured to the frame A, and to the -upper end 4ofthis shaft a bevel-pinion, c, is keyed,wl1ich v engages with the teeth oifa larger bevel-wheel,

c', on a horizontal transverse shaft, c. This shaft c2 is sustained by journal-'boxes 'd d, and

'carries vbevel spur-wheels near each'end,

which communicate rotary motion to the lowermost .drawingrollers e onl both sides' of the` frame A. By means of spur-wheels on the drawing-rolls, as shown'in Fig. 1, thse rolls are caused to turn with a slow motioinand ,fced' the roving or'yarn to the spindles in a,4

proper. manner. Thesetdrawing-rol-ls may be 'constructed-and' supported in .the usual wellclined bearings upon the .ends of 'short posts d d d,which rise perpendicularly from` a stationary horizontal rail,F. One end of the lowermost, drawing-rolle carries a ,grooved beltwheel,f,A over which a belt passes that communicates rotary motion from said roller to alarge belt-wheel, G, which .is keyed upon a wormshaft, GX, located in journal-boxes near the base of frame A, as clearly shown in Fig. 1. This wormshait operates the y'lift-motion of the spindle, a, as will be hereinaer explained.

The ring-rail J is applied to frameA in a horizontal position, and secured fast thereto by means of screws hh, whichpass through; oblong slots h', made through the frame, and Athus allow thisring-rail to be adjusted nearer to or farther from the rail F, and lheld in a position parallel to this latter' rail;

, Beneath the stationary but adjustable ring-l rail J is the bolster-rail K, and" beneath this bolster-rail and arranged parallel to it is the step-rail L, which latter rails are arranged par! allel to the ringrail, and are secured at a prop! er distance apart'by meansof posts j j. The v'ringsK upon the railJ andtheir' travelers, and also the spindles, their steps, and holsters' may all be constructed in the usual well-known v manner. The ends of the tworails K L are notched and adapted for receiving feaiherslh, y applied in vertical positions'upon the innerfaces of the frame A, which feathers serveas guides for the said rails K L in their vertical motions. The two posts j j are extended down through the stepraill L, and are received by sockets in adjustable 'steps m m,which are pivoted to the free ends of vertically-vibrating.

lifting-arms g g', which are keyed on th endsv of horizontal rock shafts H H. These two shafts have their bearings in longitudinal supporting-barsl of frame A, and are connected together by means of vertical arms p p and connecting-rod p', as shown in Fig. 1. To one 'oftheseshafta H', a loaded arm,'p, is secured,

. 2-.1 somos To the rock-shattH arms, S S, arc. rigidly applied, carrying ontheir free ends a horil zontal transverse plate, S, having'a dovetail groove in its bottom surface, which receives portion, t,.a steel tooth, 1E,"which bears upon Xf'hUS'ulface of the heart-cam. T, and is caused v to move back and forth upon this camin a direction with the length thereof, by means which'fwill behereinafter explained. The cam T v is keyed upon a .short shaft, n, which is' caused to rotate slowly by the action of a worm.- wheel, G,upona tangent. wheel, G", which latter is keyed to the cam-shaft n, as shown. v This camshaft n is supportedtin bearings I V,

and is`\adjustable for lsetting the cani'to work beneath the tooth t to the best advantage. The

slide S. receives through it a screw-rod r,which has its bearing in one end of thezvertically-vif 'brating plate S,- and which carries upon one end a ratchetlwheel, r', and abevel spur-wheel,

r yThe teethof the ratchet-wheel?J are engaged by a gravitating pawl, 1', which is pivoted to an arm, r, extending4 from plate S', and which will prevent the screw-rod Ar from turning backward. In Fig. 3- the pawl is thrown back, s o asnot to hide thcratchet. 'The spur-wheel r engages with the teeth of a spurwheel, b, which .is keyed* on a hand-wheel shaft, b, having its bearings on said arm r, by lmeans of which the tooth t' can `be run back after aset of cops have been Wound and set at any desired point upon its cam' T for repeatingthe o eration of winding. -A vibratin'gpawl,;

W,w ich has its bearing upon the cam-shaft n.,

' and which'isl loaded at one end, engages with the teeth on ratchet-wheel rfand moves this wh eel about its axis a distanceequal to the spacelbe tween each-pair of teeth of said wheel once in every rotation of thel cam-shaft n andV cam T;

and 'thus the tooth t will be caused to approach that, end of the cam T giving the least upward throw by regular movements as this came rotates and the work of winding progresses. The'cam T is of the form of a true heart-whentaken at any point in cross-section, asshown in Figs. 7 and 8, and when taken longitudinallyin the plane w 1a." its lines are parallel. 'This is shown clearly in the dagram, Fig.l 9wherein it ywill be seen that the shaft n, upon which this cam, is placed, passesobliquely throughjit, so that at .one 'end the cam will give a greater upward throw than-at the opposite end; The distance `from :vito zl at one end of the cam gives 'the ,greatestdepression to each spindle, and the distance. from e to what the same end ofthe cam gives the-greatest upward throw to each spindle.

Consequently the tooth t should be at o r near this end of the cam when thework of windand z at the 'opposite end @the cam gives the least depression to each spindle, andi-.hgh

- the least throw.

distance between the points a c gives the least upward throw to each spindle. Consequently as the tooth t' approaches this end of the cam Y supported directly uponit andmoved along from the end xtc o the end a2* ,fr-s. As the cam revolves about its axis itwill give a rapid de scending movement to the spindle between the points a." x on one side of the axis of the cam, and on equally rapid ascending movement to the spindle between thezpoin'ts .r on the opopsite side of the axis. These rapid up and down movements take place when the yarn is being wound upon the lower end of the cop,A and produce what is known as bindingthreads, for binding. the several courses of yarn securely in pla-ce, so as to prevent the cop from casually unwiuding when removed from its spindle. 'The same operation ofwinding bindinG-threads takes place at the upper end of each cop at the highest throwsof the spindle.

I will 'now refer to the operation ofthe cam as arranged in Figs. l, 3, 4, and 5. Mot-ion being imparted to the shaft Gi* of the worinscrew G from the pulley fon one of drawingnrolls e, this worm-screw 'operates upon the wheel Gt' on camshaft n, and communicates a slow. rotary motion to cam T, which cam acts upon the 'traversing tooth and gives vibrating movements to the. plate'bZ and its arms v s, which latter Aparts being applied to the shaft H will rock this shaft'. VBy means ofthe two arms p p, their connecting-rod p', and the lifting-arms y g on shafts H H', the rocking movements given to these two shafts will hommuuicate vertical reciprocating movements to the spindle-rails and their spindles, which latterinovements will vary iu` length accord' ing to the varying throws of the' heart-cam.

At the commencement of the operation the tooth t is adjusted near that end of the'cam T whichgives the greatest throw, by turning the hand-wheelshaft b5, and at every rotation of the cam T the pawl W will move the tooth t nearer to that end of this cam which gives that end ofthe cam which gives t-heleast throw, the .rising and descending strokes of the spindles a, will be gradually shortened, thereby winding the yarn upon the spindles in the form above stated. When the spindles have been filled and' the cops removed from them, the tooth t is run back by turning the handwheel shaft b5 so as to rest upon that cud of the heart-cam which gives the greatest -upward throw, to repeat the operation ot' winding. e

For the purpose of keeping the strand of As the tooth i approaches yarn centrally over their respective spindles made iu any suitable manner. Those represented in the drawings are simply short pieces of wire with their extremities coiled in the Aform of eyes thel centersA of which coincide with the vertical axes of their respective spindies. The eyes- P-guide 'the strands of yarn eye-pieces maintain a vuniorm distance from the ring-rail, so that the angle of the thread andthe resist-ance of the -air upon it will always be uniform, whatever may be the vposi,- tions of the other parts of the spinning and 'Winding devices. here the ring-raiJ is stationary, this may be done by securing the guide-wires P to thebar F, which supports rails are stationary, the guide-wiresl Bruay be secured to the ring-rail, or, if desirable, the
